FLAT-WOVEN TUBU LAR FABRIC.

SPECIFICATION forming part of Letters Patent No. 653,918, dated July 17, 1900.

Application filed July 20, 1899. Serial No. 724,477. (No specimens.)

T0 all whom, t may concern,.-

Be it known that I, ALBERT DE LAsKI, a citizen of the United States, residing at the city of Trenton, county of Mercer, and State of New Jersey, have invented certain new and useful Improvements in Flat-Woven Tubular Fabrics, of which the following is a specification.

My invention relates to a flat-Woven tubular fabric which is designed for use more particularly in vehicle-tires.

I will describe a fiat-woven tubular fabric embodying my invention and then point out the novel features in a claim.

In the accompanying drawings, Figure l is an end view of a Hat-woven fabric embodying my invention. Fig. 2 is a view of a portion of a fiat-woven fabric embodying my invention and showing the curvilinear feature thereof. Fig. 3 is a detail View of a portion of a flat-woven fabric. Figs. a and 5 are each detail views of a flat-woven fabric embodying my invention and showing the effect of the warp-threads. Fig. 6 is a view showing the embodiment of the invention in a vehicle-tire.

Similar letters of reference designate corresponding parts in all of the figures.

A represents the warp-threads, and B the weft-threads. The weft-threads B are inclined or diagonal with regard to the warpthreads. The warp-threads are of different diameters and are so arranged as to have those warps of the greatest diameter in the same part of the fabric-that is to say, in a tubular fabric those warps having the greatest diameter are adjacent in one portion of the circumference of the fabric, while those warps of lesser diameters are arranged in the remaining portion of the circumference according to their decrease in diameters. (See Fig. 1.) In the weaving of a fabric having warps of dierent diameters arranged as described a curve will be given the fabric, as shown in with suitable take-0H mechanism adapted to the curvilinear feature of the fabric may be employed, provided, of course, the shuttles carrying the weft-threads travel in a direction that is inclined or diagonal to the direction of the warps. In Fig. 4t I have shown the appearance of the fabric when the selvage ends are liattened. In Figs. 3 and 5 the incline or diagonal of the weft-threads is the reverse of that shown in Fig. 4. This is desirable when a multi-ply tubular fabric is to be made, for in such a fabric the weft-threads of one tube will cross those of another tube. In making a multi-ply fabric each tube is provided with cement or other binding medium, so that when one tube is drawn over the other they will be firmly united. This form of fabric tube is particularly desirable for use in vehicle-tires owing to its curvilinear heavytread feature and the warps of different diameters, those warps of the greatest diameter being used for the tread side of the tire. If the fabric tube is to be used in vehicle-tires, I preferably treat the different threads comprised in the fabric with a rubber solution preparatory to their being woven, which renders them impervious to moisture, dac.

' In makinga tire any number of fabric tubes may be employed, according to the ply tire desired and the use to which the tire is to be put. At least two tubes are used in each tire, and when placed one over the other the Wefts have the appearance shown in Fig. 6. The ends of the tubes may be united in any desired manner and a rubber covering applied to the fabric tubes and the whole vulcanized in any desired manner. An inner tube may be used, if desired, in which case an opening is made in the fabric tubes which is closed with a lacing.

What I claim as my invention is- In a tire, a plurality of woven-fabric tubes IDO each of which comprises Warp-threads of difname to this specification in the presence of ferent diameters and inclined or diagonal two subscribing Witnesses.

weft-threads, said tubes being arranged one within the other, and the weft-threads of one ALBERT DE LASKI 5 tube crossing the weft-threads of the adja- Vitnesses:
